Photo by: A.L. Antonelli
Use IPM (Integrated Pest Management) for successful plant problem management.

Biology
Aphids on photinia are variously colored, from yellowish or greenish to black. They are soft-bodied insects less than 1/8" long. Aphids often feed in large groups and typically are found on new growth, including both leaves and shoots. Heavy infestations can cause yellowing or wilting of foliage. New growth may be stunted. Aphids often produce honeydew, a sweet, sticky material that may attract ants or become covered with a growth of dark sooty mold.
